Compared with traditional split servo motors, integrated servo motors reduce the number of external connection components, reduce the complexity and cost of the system. In addition, due to the integrated design, integrated servo motors also have advantages in performance, such as higher precision and faster response speed.

2.Basic working principle of integrated servo motor When the integrated servo motor receives a pulse, it will rotate the angle corresponding to the pulse to achieve displacement. Since the integrated servo motor itself has the function of sending pulses, each rotation angle will send a corresponding number of pulses, so that the system can know how many pulses are sent to the servo motor and how many pulses are received back, so as to accurately control the rotation of the motor and achieve precise positioning with an accuracy of 0.001mm.

3.Structure of integrated servo motor 1.Stator: The stator is mainly made of laminated silicon steel sheets and is used to fix the magnetic field of the motor. The stator is the stationary part of the motor. After the winding is energized, a rotating magnetic field is generated to provide a power source for the operation of the motor. ‌2.Rotor: The rotor is usually composed of permanent magnets or electromagnets and is the rotating part of the motor. In permanent magnet servo motors, the rotor has built-in permanent magnets and can generate a magnetic field without external power supply. The rotor begins to rotate under the action of the rotating magnetic field generated by the stator, converting electrical energy into mechanical energy to drive the load to operate. ‌3.Encoder: The encoder is used to monitor the position and speed of the motor in real time and feed this information back to the control system to form a closed-loop control. Common encoders are photoelectric encoders and magnetic encoders. The encoder is a key component for achieving high-precision control of integrated servo motors. ‌4.Bearings and end covers: The bearings are used to support the rotation of the rotor to reduce friction and wear; the end covers are used to seal the inside of the motor to prevent dust and moisture from entering. These components together ensure the stable operation and long life of the motor. ‌5.Controller: The controller is the core component of the integrated servo motor and is mainly responsible for controlling the speed, position and other parameters of the motor. The controller usually uses a digital signal processor (DSP) or a microcontroller (MCU) chip, which has the characteristics of high-speed computing and high-precision control. 6.Driver: The driver is the power source of the integrated servo motor and is mainly responsible for converting the motor's control signal into a motor drive signal. Drivers usually use power semiconductor devices such as MOSFET, IGBT, etc., which have the characteristics of high efficiency and high reliability. 7.Sensor: The sensor is mainly used to detect the position, speed, acceleration and other parameters of the motor, and feed this information back to the controller and driver. Common sensors include encoders, Hall elements, potentiometers, etc.

4.Performance optimization method of integrated servo motor 1.Motor selection and parameter adjustment: Select a suitable servo motor according to actual needs to avoid waste or insufficiency caused by excessive or insufficient power. Adjust the motor's inductance, resistance, rotor inertia and other parameters to improve the motor's response speed and accuracy. 2.Optimize the transmission system: Reduce friction and inertia loss in the transmission chain, use low-friction transmission devices and efficient transmission ratios, and significantly improve transmission efficiency. Redesign the mechanical structure, reduce the inertia of components, or optimize the mechanical motion trajectory to reduce the load and thus increase the motor speed. 3.Application of advanced control algorithms: The use of advanced control algorithms, such as vector control, direct torque control, fuzzy control, neural network control, etc., can greatly improve the control accuracy and response speed of the servo motor. 4.Regular inspection and maintenance: Regularly inspect and maintain the integrated servo motor, including cleaning, lubrication, tightening, etc., to ensure that the motor is in good operating condition. Once a motor fault or abnormality is found, it should be handled in time to avoid the expansion of the fault and cause greater damage to the motor. 5.Power supply stability: The integrated servo motor has high requirements on the quality of the power supply, and the power supply voltage fluctuation will directly affect the speed control accuracy and response speed of the motor. Therefore, it is necessary to ensure that the power supply voltage is stable within the rated range, and the power supply waveform can be trimmed by adding filtering circuits. 6.Heat dissipation optimization: In the process of improving the performance of the integrated servo motor, pay attention to the heat dissipation of the motor. By improving the heat dissipation design, such as adding heat sinks, using fans or liquid cooling systems, etc., ensure that the motor will not affect performance due to overheating when running at high speed. 7.Feedback system debugging: It is very important to ensure the accuracy and stability of the encoder or sensor. Perform calibration and inspections regularly to ensure the accuracy of the feedback system and handle any abnormalities promptly. ‌8.Advanced debugging tips: Use vibration analysis tools to identify mechanical vibration problems and reduce vibration and resonance by adjusting and balancing the components of the transmission system.

The Road to Reliable AI with Hamming CEO, Sumanyu Sharma

TL;DR: Sumanyu Sharma is the Founder & CEO of AI startup, Hamming. He’s been obsessed with AI forever—from academic research to production systems at Tesla—and he has an uncommonly well-rounded view of what it takes to make AI actually work. In this wide-ranging interview, Sumanyu shares how Hamming is tackling the key challenges of AI reliability through prompt tuning, evaluation, and observability. He also dives into the thorny questions around governing AI's risks and societal impacts. Read Sumanyu's interview for a nuanced take on what responsible AI development looks like and why reliability is the key to unlocking the technology's full potential.

Sumanyu, thanks for making the time to do this. Let's kick things off with how you first got hooked on AI - was there a lightbulb moment that set you on this path or was it a gradual build up?

I've always been fascinated by systems that learn and improve with more data or repetition, whether it's human or AI systems. As a kid, I used spaced repetition techniques to retain information better and optimize my own learning. This early interest in self-optimization set the stage for my passion for AI. During my undergrad at the University of Waterloo, I got my first taste of real-world AI—back then it was called machine learning.

“My "aha" moment came when I took Andrew Ng's class on Coursera and built a hand digit classifier that actually worked. It was incredible to see that machines can learn and improve with more data, just like humans.”

The realization that I could build systems capable of learning and adapting on their own was a game-changer for me. Since then, I've been hooked on systems that get better with more data. I took courses to learn the fundamentals of AI, pursued internships to gain practical experience, and worked with research groups at my university to dive into academic research.

I was fortunate to drive massive business outcomes using AI at Tesla and later at Citizen, sometimes with simple models, sometimes with complex ones.

When ChatGPT launched, I became obsessed with how LLMs work and what they can do, quickly becoming a daily active user and a power user. The pace of improvement in the AI space since then has been breathtaking.

At places like Tesla, Citizen, or even back in college - what were some of the key experiences that made you recognize the need for more reliable AI systems?

“Lack of reliability has always been the #1 issue limiting the widespread use of machine learning across various fields. Generative AI is just a new flavour of an old problem.”

During my time at the University of Waterloo, I aimed to help radiologists diagnose patients more accurately and quickly by leveraging past records of similar X-rays. This idea seemed obviously useful, but achieving reliable results was challenging. We developed a feature extraction technique by stacking auto-encoders into binary vectors to semantically search for similar medical images. While we got results good enough to post an arXiv paper, they weren't reliable enough for clinical settings, where a misdiagnosis could harm real patients. This experience highlighted the gap between academic success and real-world reliability, underscoring the need for more robust AI systems.

At Tesla, I encountered a similar issue but on a larger scale. Humans are terrible drivers—94% of motor vehicle accidents are caused by driver error. Building Level 5 autonomy could save thousands of lives each year. It took Waymo eight years to develop a system reliable enough for production. Tesla's approach is different but still not reliable enough for use without human supervision. Working on these projects made it clear how crucial reliability is for AI applications that impact human lives. The stakes are incredibly high, and any system that isn't 100% reliable can't be trusted to operate autonomously in critical situations.

I believe current multi-modal models face similar reliability challenges as early autonomous systems. While foundational models continue to improve, there remains a significant gap between their raw capabilities and the ability to translate these capabilities into reliable AI products and services.

“Businesses need AI systems that can consistently deliver accurate results in real-world conditions, not just in controlled environments or simulations.”

Moreover, this reliability gap isn't just a technical issue but also a matter of trust. Users need to trust that AI systems will perform as expected without causing unintended harm. This trust is built through rigorous testing, transparent operations, and continuous improvement. As AI systems become more integrated into our daily lives, ensuring their reliability will be paramount.

Your background spans publishing AI research, product leadership, leading data science teams, and driving strategic initiatives. How did wearing all those hats shape your approach and priorities at Hamming?

Well, I've been fortunate to have a diverse background.

Having done research in medical image search and deep learning, I have some intuition for fruitful research-oriented work streams. For example, we recently benchmarked major LLMs—GPT-4, Opus, Gemini 1.5 Pro, and Llama 3 70B—on codegen tasks by partnering with the University of Waterloo. This study was pretty popular on Reddit and within the YC community, and we plan to do more work like this.

My background in growth and data also provides a sixth sense of the growth rates we need to hit, what's realistic for fundraising and internal planning, as well as how to properly impact size and prioritize new features as Hamming scales.

And having been an engineer, I have a decent grasp of the engineering talent required at each stage, making collaboration with our technical team that much smoother without heavily relying on external judgement.

“I would be a significantly worse CEO without the critical skills I learned along the way before co-founding Hamming.”

Because I have a deep understanding of the entire product, engineering, research, and go-to-market landscape, I can make decisions quickly and decisively.

Can you walk us through the early days of founding Hamming? What were the biggest challenges in going from an innovative idea to an actual product and business?

The core idea for Hamming started from an evals script I wrote to solve a customer's pain point when building their RAG pipeline. The goal was to make changes to any part of the retrieval pipeline and get quantitative feedback on metrics like accuracy, hallucinations, and latency in minutes—unlike the typical vibe-checking outputs on a handful of examples in a prompt playground.

I found myself spending more time fixing the script, which was supposed to accelerate my feedback loop, than doing the actual work. This felt unusually hard, and I realized others must be experiencing the same problem.

So, I teamed up with Marius, my co-founder and CTO, to build a platform to solve this problem more comprehensively. This was definitely a "scratch your own itch" founding story.

Going from zero to one is brutal. Everything is manual, and there are no A/B tests because you don't have enough users. You have to do things that don't scale to get a handful of paying customers and do everything possible to make them love your product.

“My conviction in the problem space grows with every user I speak to. Most teams tell me that reliability is the #1 concern stopping them from shipping AI products to their customers.”

We've shipped prompt tuning, evaluation, and observability, but there's a lot more to do. We're releasing a new product every month, each tackling a different aspect of reliability.

It seems your platform components—prompt tuning, evaluation, and observability—form a cohesive solution. Can you give us an overview of how they work together to increase AI reliability for enterprises?

That's right. Prompt tuning, evaluation, and observability work together to drive reliability in a piecewise fashion.

Most teams start by writing basic prompts to quickly prototype a solution to their problem. It's easy to get 60% of the results with 20% of the effort.

“Improving prompts from 60% to 95% is extremely painful. Our prompt tuner samples the prompt solution space, tries hundreds of new prompts, and quickly returns the optimal prompt with its quantitative performance on a dataset.”

This prompt tuning heavily relies on evaluation to find the best prompts. As you move beyond prompts, you'll find it's challenging to improve the retrieval performance of RAG-based systems. RAG systems can fail during retrieval (failing to fetch the correct documents) or reasoning (failing to reason with the correct documents passed to the LLM).

We've built RAG-specific model-based evaluators that help teams differentiate between these error types. This allows teams to focus on improving their retrieval pipeline if retrieval is the bottleneck or their prompts if hallucinations are the primary issue.

Similarly, tool use is often unreliable when building AI agents. Common failure modes include improper arguments returned, wrong functions called, or hallucinated functions/parameters. We've built a function definition optimizer that tests different function call definitions to get the best results.

The combination of prompt tuning, RAG evaluations, and function definition optimization saves teams hundreds of hours per week during development. As you launch your AI products into production, you need to deeply understand how users are interacting with them beyond just token usage, latency, and other basic metrics.

Our observability tools provide this insight, helping you ensure ongoing reliability and user satisfaction.

One of your key value propositions is "reliable AI in weeks" vs months. What core innovations allow for such a rapid development cycle?

“The biggest bottleneck in building reliable AI systems comes from having humans in the loop. Without LLMs to speed up iteration velocity, making changes to your prompt, retrieval pipeline, or function definition, requires a human to check if the change improved accuracy or increased hallucinations. But humans are slow, expensive, and unreliable.”

It's impossible for a human to check every single edge case by hand. As a result, you can run a maximum of 2-3 experiments per week with this human-in-the-loop approach. This is why most AI products take months or even years to become reliable enough for teams to feel comfortable shipping. Even after shipping something to production, teams are nervous about making changes that could cause regressions for end customers.

LLMs, however, are great at reasoning and can measure accuracy, tone, hallucinations, and other quality metrics 20 times cheaper and 10 times faster than humans. LLMs will only continue to get smarter, making iteration feedback cycles even faster.

“By using LLMs as judges and leveraging them to generate optimized prompts and function definitions, teams can run 10 experiments per day.”

We spend a lot of time fine-tuning LLM evaluators to model human preferences because an LLM's definition of good may not be the same as a human's. We work closely with each customer to build their own custom evaluators to ensure the highest accuracy and relevance.

This ability to rapidly iterate and improve using LLMs is what allows us to deliver reliable AI in weeks rather than months. By automating the evaluation process and optimizing every step of the development cycle, we significantly cut down the time required to achieve robust, reliable AI systems.

I'm interested in hearing more about Hamming's prompt tuning capabilities. How does auto-generating optimized prompts improve performance vs manual approaches?

Writing high-quality and performant prompts by hand requires enormous trial and error. Here's the usual workflow:

Write an initial prompt.

Measure how well it performs on a few examples in a prompt playground.

Tweak the prompt by hand to handle cases where it's failing.

Repeat steps 2 & 3 until you get tired of wordsmithing.

What's worse, new model versions often break previously working prompts. Or, say you want to switch from OpenAI GPT3.5 Turbo to Llama 3. You need to re-optimize your prompts by hand.

Our take: use LLMs to write optimized prompts for other LLMs.

Describe the task you want to accomplish.

Add examples of input/output pairs that best describe the task.

Start optimizing.

Behind the scenes, we use LLMs to generate different prompt variants. We use an LLM judge to measure how well a particular prompt solves the task by measuring performance on the input/output pairs you described. We capture outlier examples and use them to improve the few-shot examples in the prompt. We run several "trials" to refine the prompts iteratively.

This is very similar to how metaheuristic optimization algorithms like genetic algorithms and simulated annealing find global optimal solutions by intelligently sampling the search space. The benefits are obvious.

“No more tedious wordsmith-ing. No more scoring outputs by hand. No need to remember to tip your LLM or ask it to think carefully step-by-step. Using LLMs to auto-generate optimized prompts drastically improves performance compared to manual approaches, saving you time and effort while ensuring consistent, high-quality results.”

Shifting gears to a more tactical question - as a founder, I'm sure you've leveraged many SaaS tools to power Hamming's growth and operations. Across customer experience, employee engagement, sales intelligence, productivity, and security - what have been some of your favorite tools that you consider indispensable in your stack? Any hidden gems more founders should know about?

We love supporting other YC companies, and we use a variety of SaaS tools to power Hamming's growth and operations. Here are some of our favorites across different areas:

Customer Support: We use Atlas (YC) for customer support. It's been a game-changer for managing customer interactions.

Sales Intelligence: For sales, we use a combination of Apollo (YC), LinkedIn, and Dripify. This mix helps us talk to people who care about what we're building.

Productivity: I'm a huge fan of Superhuman for emails—it makes managing my inbox a breeze. Superwhisper is great for speech-to-text, Warp (an AI-first terminal) saves me time from having to remember bash commands, and Cursor (an AI-first VSCode fork) makes our eng team at least 3x faster. For task management, I rely on Sunsama for personal tasks and Linear for managing engineering tasks.

Code Management: We use Greptile (YC) for semantically searching across our entire codebase and automating PR reviews, and Ellipsis (YC) for additional PR review support.

Documentation: Mintlify (YC) is our go-to for documentation. It makes creating and maintaining high-quality docs easy and efficient.

These tools are indispensable in our stack, and I highly recommend them to other founders. They help us stay productive, organized, and focused on what matters most - talking to customers and making something people want.

Talent capable of building robust AI products is liquid gold—expensive and in high-demand. How has Hamming been able to attract and retain a high caliber team despite this challenge?

You're totally right. At Hamming, we've been fortunate to attract and retain a talented team so far by emphasizing our mission and creating a culture of complete freedom and ownership.

Our team is passionate about making AI reliable for all enterprises. There's no silver bullet to reliability—we need to solve many problems along the way to achieve this goal. Our internal success criteria is for every enterprise to use Hamming to build AI products. The team won't stop until we get there.

Many organizations are extremely top-down, with CEOs pushing half-baked ideas down the product and engineering teams' throats. At Hamming, we believe the best ideas come from within the organization and from insights gained by talking to customers. This is especially true in our space, where the market is changing rapidly.

“Anyone in our org can propose an idea, show why it's a good idea, how many customers it can impact, and then execute on it without needing top-down buy-in from me or anyone else.”

This inclusive and empowering culture drives our success and keeps our team motivated and engaged.

And with great freedom comes total ownership. When someone executes an idea and it doesn't work, they take complete ownership of the outcome, and propose a plan to either wind it down or present new adjacent ideas based on what they learned.

The combination of having a compelling mission and a culture that treats people like adults that keeps our team grinding every single day, seven days a week.

Unreliable AI systems can lead to serious issues like the Air Canada chatbot incident. What processes or guardrails does Hamming have to prevent such brand risks or violations of business policies?

Absolutely. That was a huge wake-up call for enterprises using the "move fast and break things" mentality to ship unreliable AI products. Another instance was New York City's "MyCity" AI chatbot, which ended up hallucinating and accidentally telling users to break the law.

For example, when asked if an employer can take a portion of their employees' tips, the bot responded affirmatively, despite the law stating that bosses are not allowed to take employee tips.

Preventing brand risks and violations of business policies requires a comprehensive, multi-pronged approach. Here's how we tackle it at Hamming:

Prompt Reliability: Every prompt in your system needs to be reliable, version-controlled, and audited for robustness against prompt injection attacks. Our prompt tuning product helps businesses create prompts that are more reliable and less susceptible to such attacks.

Evaluation for RAG & AI Agents: Our evaluation solution helps teams measure and minimize hallucinations during development. Every time a team makes a change to the prompt or retrieval pipeline, they can rely on Hamming to detect regressions and identify areas for improvement.

Proactive Red-Teaming: We conduct proactive red-teaming on existing AI systems to test their resilience against known prompt injection attacks or malicious inputs. This adds an extra layer of safety before teams deploy their products to production.

Guardrails: We're currently building AI guardrails that act as an internal firewall, preventing unwanted, harmful, or inaccurate statements from ever reaching your end users.

“By making prompts resilient, using evaluations to measure and minimize hallucinations, proactively red-teaming to ensure robustness against prompt injection attacks, and using guardrails as a final firewall, enterprises can safely deploy their AI products to production and keep them secure.”

You've described 2023 as the "year of demos" and 2024 as the "year of reliability". Looking ahead, what do you see as the next frontier or major challenge facing widespread enterprise AI adoption in 2025 and beyond?

I think reliability will continue to be a challenge in 2025 and beyond. The shape of 'reliability' will evolve—what's hard today may be easier tomorrow, but new attack vectors will emerge. For example, most LLMs are trained on publicly available data, often scraped from websites. A rogue actor, possibly a government, could create poisoned datasets to corrupt the pre-training process and subtly bias model outputs. I recently learned about a front-running poisoning technique targeting web-scale datasets that periodically snapshot crowdsourced content—such as Wikipedia—where an attacker only needs a time-limited window to inject malicious examples. We'll need new solutions to check the integrity of the datasets used to train LLMs.

Governance will also be a significant challenge. As AI models become more powerful and ubiquitous, enterprises will face increased scrutiny to ensure their AI systems are used safely, ethically, and without bias.

“Regulatory frameworks will likely become more stringent, requiring companies to demonstrate compliance with new standards. And this regulatory burden��� could introduce significant friction, making it harder to innovate rapidly.”

Organizations will need robust governance frameworks to manage compliance while still fostering innovation. Ensuring AI operates ethically and without bias will be paramount. As AI systems influence more aspects of society, the demand for transparency and accountability will grow.

Enterprises will need to implement comprehensive bias detection and mitigation strategies, ensuring their AI models do not perpetuate existing inequalities or introduce new biases. Developing explainable AI (XAI) will be crucial to provide insights into how models make decisions, thereby building trust with users and regulators.

Security and privacy concerns will also be more pronounced. Protecting sensitive data from breaches and ensuring individual privacy will be critical. AI systems must be robust against adversarial attacks, where malicious actors attempt to deceive or manipulate AI behavior. Strong security measures and maintaining data privacy will be essential to safeguard both the technology and its users.

Finally, the environmental impact of large-scale AI deployments, particularly the energy consumption of training and running complex models, will become a significant concern. Enterprises will need to adopt more sustainable practices, such as optimizing algorithms for efficiency and leveraging green computing resources. Balancing the benefits of AI with its environmental footprint will be a key consideration for future AI strategies.

As Hamming deploys AI systems at scale there's power - but also responsibility. What's your take on governing the ethical risks and societal impacts of such powerful technologies?

Deploying AI systems at scale comes with significant responsibility. AI has the potential to revolutionize industries and improve lives, but it may also displace millions of jobs. As research teams advance foundational models, everyone is learning and adapting to this new reality. While I don't have deep expertise in risk mitigation, I can offer a few ideas.

Firstly, transparency is crucial. Our AI systems must be explainable, providing clear insights into how decisions are made. This builds trust with users and regulators, ensuring our technology isn't a black box but a tool that can be understood and scrutinized. I admire the work Anthropic has done in making their models more explainable and easier to trust.

Secondly, we need robust frameworks to detect and mitigate bias. AI systems should not perpetuate existing inequalities or introduce new biases. Continuous monitoring helps detect and address biases as they emerge. Beyond technical solutions, fostering a diverse team with contrarian opinions is essential in managing these risks.

Thirdly, privacy and security are non-negotiable. Protecting sensitive data from breaches and ensuring individual privacy will become even more important.

Fourth, on the regulation side, we need to create robust frameworks that balance the need for innovation with the imperatives of safety and ethics.

In essence, governing the ethical risks and societal impacts of AI requires a multi-faceted approach. At Hamming, we are committed to building not just powerful AI systems, but responsible ones.

What responsibilities do you believe AI companies should have in terms of pressure-testing for biases, discrimination, or potential harms before releasing systems?

Both foundational AI companies and application-focused AI companies have an enormous responsibility to ensure their systems are thoroughly pressure-tested for biases, discrimination, and potential harms before release.

At Hamming, our evaluation, continuous monitoring, and red-teaming services rigorously evaluate models and AI systems for any signs of bias or discrimination. We use diverse datasets that reflect the real-world scenarios our customers' systems will encounter. By simulating various edge cases and stress-testing the models in controlled environments, we can identify and mitigate risks early on.

Secondly, transparency and alignment are key. The more we understand about how these AI systems work, the better we can align them to reflect human preferences, confidently eliminating bias, discrimination, and other potential harms.

Moreover, continuous monitoring post-deployment is essential. Implementing feedback loops to measure real-world performance ensures that the systems remain fair and effective over time.

At Hamming, we take pressure-testing for biases, discrimination, and potential harms seriously. By doing so, we can ensure that our AI systems are not only powerful but also just and beneficial to all.

Looking 5-10 years out, what types of guardrails—whether regulation, compliance, dynamic monitoring, or other safeguards—do you believe will be critical for responsible AI development?

Looking 5-10 years out, the most exciting AI use cases are in regulated industries like healthcare, financial services, and law. All four areas you mentioned—regulation, compliance, dynamic monitoring, and guardrails—are crucial for using AI safely, fairly, and without systemic bias.

Firstly, we need a sensible regulation framework. As AI systems become more integrated into critical sectors, clear and enforceable regulations will help ensure these technologies are developed and deployed responsibly. Regulations should focus on transparency, accountability, and fairness, setting standards that are logical and don't slow down innovation too much.

Compliance is equally important. AI companies must develop and maintain comprehensive compliance programs that align with regulatory requirements. This includes regular audits, documentation, and adherence to best practices to ensure ongoing compliance.

Dynamic monitoring will be crucial for maintaining the integrity and reliability of AI systems. We continuously monitor, detect, and mitigate potential biases, errors, or malicious activities on behalf of our customers before they cause harm.

Guardrails, including ethical guidelines and operational safeguards, are necessary to guide AI development. These guardrails should be embedded throughout the AI lifecycle, from design to deployment.

Additionally, fostering a culture of responsibility within AI companies is pretty vital. Education and training programs that emphasize ethical AI development, coupled with a commitment to transparency and accountability, will help build a foundation for responsible innovation. Encouraging collaboration with external stakeholders, including policymakers, ethicists, and the public, will further strengthen the guardrails around AI development.

We've covered a lot of ground today. Before we wrap up, is there anything else you'd like to add or emphasize in terms of Hamming's mission and the future you envision? What final thoughts can you leave us with?

Our mission is making AI reliable.

“We believe every company is already an AI company or will become an AI company in the future.”

We imagine a world where we can help every enterprise build self-improving and reliable systems that unlock trillions in economic value and significantly speed up innovation in all areas - especially science and technology.

How to improve the accuracy of closed-loop stepper motors

1.What is the role of closed-loop stepper motors The role of closed-loop stepper motors mainly includes high-precision position and speed control, improving the response speed and acceleration performance of the system, enhancing the load capacity and efficiency of the system, and achieving low-noise and low-vibration operation. ‌ Closed-loop stepper motors achieve high-precision position and speed control by introducing position feedback and speed feedback, which significantly improves the control accuracy and stability of the entire system. This feedback mechanism enables the closed-loop stepper motor to respond to operating instructions more quickly, thereby improving the response speed and acceleration performance of the system. In addition, by better controlling the speed and acceleration of the motor, the closed-loop stepper motor enhances the load capacity of the system and improves the efficiency of the system. Finally, due to the ability to better control the operation of the motor, the closed-loop stepper motor achieves low-noise and low-vibration operation, thereby improving the reliability and stability of the entire system.

2.Working principle of closed-loop stepper motors The closed-loop stepper motor is an intelligent drive device that is widely used in the fields of machinery, automation, and electronic equipment. Its working principle is based on magnetic field interaction and current application. Specifically, when the external driver sends a control signal to the motor, the motor changes the current according to the signal to achieve rotation. At the same time, the encoder inside the closed-loop stepper motor monitors the position of the rotor in real time and feeds this information back to the control system. The control system precisely controls and positions the motor based on the information provided by the encoder, thereby achieving high-precision motion control. This closed-loop control method enables closed-loop stepper motors to have the advantages of high precision, high speed, and high reliability, and can accurately control the position and speed of the rotor, thereby achieving high-precision positioning and motion control. Compared with traditional open-loop stepper motors, closed-loop stepper motors achieve more accurate position feedback and control system adjustment through internal encoders, providing higher positioning accuracy and more reliable performance.

3.Precautions for using closed-loop stepper motors ‌1.Correctly connect the line sequence of the encoder and the stepper motor. Make sure that the line sequence of A+, A-, B+, and B- is correctly connected to avoid the "Phase Line Error!" error. If this error occurs, the line sequence of the motor should be readjusted after power off. ‌2.Keep the drive well ventilated. The drive of the stepper motor is not sealed, so care should be taken to ensure good ventilation during use to avoid overheating damage caused by long-term operation. ‌3.Prevent metal shavings and dust from falling into the driver. Since the driver board of the stepper motor is not sealed, metal shavings and dust should be prevented from falling into it during use to prevent short circuits and motor damage. ‌4.Pay attention to the positive and negative connections of the power supply. When plugging in the power supply, be sure to pay attention to the correct connection of the positive and negative labels to avoid burning the driver due to incorrect positive and negative connections. ‌5.Connect the basic system step by step. When connecting the circuit of the stepper motor, do not connect all the circuits at the beginning. You should gradually connect them into the most basic system, and then gradually increase the connection after confirming that it is running well. ‌6.Observe the state of the motor. Within half an hour of starting to run, you should closely observe the state of the stepper motor, such as whether the movement is normal, the sound and the temperature rise. If you find any problems, you should stop and adjust them immediately.

4.Ways to improve the accuracy of closed-loop stepper motors ‌1.Hardware connection and encoder installation: By installing an encoder, the stepper motor can achieve full closed-loop control and improve positioning accuracy. The use of encoders can be based on the segmentation requirements, with different levels of resolution, for real-time feedback, thereby achieving precise control of the stepper motor. ‌2.Origin control: According to the Z signal of the encoder, the coordinate origin is identified and calculated. In this way, the accuracy can reach a certain standard, ensuring that the stepper motor can accurately return to or locate to the specified origin position. 3.Out-of-step control: According to the feedback data of the encoder, the output pulse is adjusted in real time, and corresponding out-of-step adjustment measures are taken to ensure the stable operation and precise position control of the stepper motor. ‌4.Optimized current control method: Through PWM control and current attenuation mode, the step error problem under low-speed operation or positioning control, as well as the torque instability problem under high-speed operation, are solved, thereby improving the operation quality and positioning accuracy of the stepper motor. ‌5.Reduce the step angle and increase the number of beats: The accuracy of the stepper motor can be increased by reducing the step angle or increasing the number of beats. When the double beat system is adopted, the step angle is reduced by half, thereby improving the working accuracy. ‌6.Increase the number of rotor teeth‌: Increasing the number of rotor teeth can also reduce the step angle, thereby reducing the error of motor operation and improving positioning accuracy‌.

How to adjust the dip switch of the stepper motor driver

1.Explanation of stepper motor driver The stepper motor driver is an actuator that converts electrical pulses into angular displacement, which is mainly used to control the rotation and movement of the stepper motor. It realizes the drive of the motor by converting the control signal into the drive signal of the motor. The stepper motor driver is generally composed of a pulse generator, a power module, a signal decoder and a drive module. The pulse generator is used to generate a control signal (pulse signal) to control the movement of the motor; the power module provides power to the motor so that the motor can operate normally; the signal decoder converts the pulse signal into a motor drive signal to control the operation of the motor; the drive module is used to amplify the motor drive signal to provide sufficient power to drive the motor. ‌

2.Classification of stepper motor drivers 1.Voltage driver: It controls the speed and position of the stepper motor by changing the drive voltage. This driver is characterized by simple structure and low cost, but poor dynamic performance, easy to heat up and lose step. ‌2.Constant current driver: It drives the stepper motor by controlling the current to ensure that the current of the motor remains constant during operation. This type of driver is characterized by good dynamic performance and low heat generation, but the structure is relatively complex and the cost is high. ‌3.Microstep driver‌: It is a high-precision drive method that achieves more detailed position control by dividing the basic step of the stepper motor. This driver has the characteristics of high precision, low vibration and low noise, and is suitable for application scenarios with high precision requirements. ‌4.Closed-loop driver‌: By adding an encoder or other sensor to achieve real-time feedback on the position of the stepper motor, high-precision position control is achieved. This driver has the characteristics of high precision, high dynamic performance and low step loss rate, but the structure is relatively complex and the cost is high.

3.Reasons for stepper motor driver alarm 1.Power supply problems‌ are one of the common reasons for stepper motor driver alarms. This includes unstable power supply voltage, too high or too low power supply voltage, poor power supply line contact, and power switch failure. Solutions to these problems include checking whether the power supply voltage meets the requirements, adjusting the power supply voltage in time, repairing or replacing the power supply line contact, and checking and replacing the power switch‌. 2.Motor problems‌ may also cause stepper motor driver alarms, including motor damage, poor contact between the rotor and stator, and winding short circuit. Solutions to motor failures may include checking whether the motor is overheating and whether it needs to be replaced or maintained, such as cleaning and lubrication. 3.Control signal problems are also an important factor, including poor contact of the control signal line, controller failure, and unstable control signal voltage. Solutions to these problems may involve repairing or replacing the control signal line, checking and replacing the controller, and adjusting the control signal voltage. 4.Problems with the driver itself, such as a damaged or improperly adjusted driver, can also cause alarms. Solving these problems may require replacing the driver or adjusting the driver settings.

4.How to adjust the stepper motor driver dip switch 1.Understand the basic principles of stepper motor drivers A stepper motor driver is an electronic device used to control stepper motors. It converts current into signals that the stepper motor can understand, thereby driving the motor to rotate precisely. Before adjusting the dip switch, you need to understand the basic principles of the stepper motor driver. 2.Determine the working mode and parameter settings Before adjusting the dip switch of the stepper motor driver, you first need to determine the working mode and parameter settings. The working mode can be full-step mode, half-step mode or micro-step mode; parameter settings include step angle, acceleration, drive current, etc. 3.Consult the instruction manual of the stepper motor driver Stepper motor drivers are usually equipped with an instruction manual, which contains detailed parameter settings and information about the dip switches. Before making adjustments, read the instruction manual carefully to understand the location and corresponding functions of the dip switches. 4.Locate and adjust the dip switches According to the instruction manual of the stepper motor driver, locate the dip switches on the driver. Dip switches are usually a row of small switches that can be set to different functions and parameters by toggling. Before adjusting the dip switches, it is recommended to turn off the power supply to avoid short circuits or other damage to the circuit. 5.Adjust the dip switches as needed Adjust the dip switches from one position to another as needed. When adjusting the dip switches, carefully check the information in the instruction manual to ensure that they are adjusted to the correct position. Some dip switches may have multiple options, while others may only have two options (on/off). 6.Start and test the stepper motor driver After the adjustment is completed, reconnect the power supply and start the stepper motor driver. According to the working mode and parameter settings of the driver, perform corresponding tests to ensure that the motor can rotate as expected. If other parameters need to be adjusted, you can refer to the instruction manual again and repeat the above steps. 7.Test and application of the adjusted stepper motor driver Once the dip switches of the stepper motor driver are successfully adjusted, some tests and practical applications can be performed. In the test, you can verify whether the set working mode and parameters are as expected. In the application, you can connect the stepper motor driver to the corresponding equipment or system to achieve the desired functions and performance.

Understanding CNC Machines: An In-Depth Look at Their Components

CNC (computer numerical control) machines are sophisticated pieces of equipment designed to automate the manufacturing of parts from a variety of materials, including metal, plastic, and wood. These machines come in various configurations, with CNC mills and CNC lathes being the most common. CNC lathes are ideal for processing cylindrical parts, while mills are versatile enough to handle flat, curved, or angular parts.

This article will explore the different components of a CNC machine. Some parts are common to both lathes and mills, such as the control unit, driving system, and feedback system, while others are specific to certain types of machines. For instance, tailstocks and headstocks are unique to CNC lathes.

1. Input Device

The input device is how CNC programs are loaded into the machine. This can be done through a keyboard (to directly input G-code commands), a USB flash drive (to transfer a program from another computer), or wireless communication (to download a program from another computer over a network).

2. Machine Control Unit (MCU)

The MCU is the brain of the CNC machine. It comprises electronic hardware and software that interpret the G-code provided by the input device and translate it into instructions for the tool drivers. The MCU controls the movements of servo motors along the machine’s axes and processes feedback from sensors to ensure precise tool positioning. It also manages tool changers and coolant activation as specified by the G-code.

3. Machine Tools

Machine tools refer to any tools that perform processes on a workpiece, usually cutting tools. CNC lathes use stationary tools and rotate the raw material to make cuts, whereas CNC mills move spinning tools into stationary material. Advanced 5-axis machines can move both the tool and the workpiece, enabling the creation of more complex features. Machine tools are stored in “tool libraries,” and a tool changer automates the swapping of tools during operations.

4. Driving System

The driving system consists of the motors that move the tool along the machine’s axes. In a standard CNC mill, the bed moves horizontally along the x- and y-axes, while the cutting tool moves up and down along the z-axis. In a CNC lathe, the driving system moves the cutting tool along the rotational axis of the workpiece. Movement is often controlled by servo motors, ball screws, and linear guides to ensure precision.

5. Feedback System

A feedback system is essential for maintaining accuracy. It uses a closed-loop control system to verify and adjust the position of mechanical components after movement. This can be achieved with linear or rotary encoders attached to the servo motors. Special probing tools are also used to measure the actual part during machining, ensuring dimensional accuracy.

6. Display Unit

The display unit is a screen that shows crucial information to the operator. Some units have large, high-resolution screens displaying extensive data, while others have smaller, low-resolution screens showing only essential information. The display unit allows the operator to input G-code, change machine settings, and monitor the machine’s status.

7. Bed

The bed of a CNC mill is where the raw material is mounted. Various work-holding jigs secure the workpiece in place, often using t-slots or holes for attachment. In a CNC lathe, the tool turret and tailstock are mounted to the bed, and the raw material is secured in the chuck.

8. Headstock

The headstock is specific to lathes and contains the main drive, bearings, and gears needed to rotate the chuck. Located on the left side of the lathe, the headstock is usually enclosed and accessed via removable panels.

9. Tailstock

The tailstock supports long, cylindrical workpieces on one side while the chuck supports the other, preventing deflection during cutting. The tailstock can move along the lathe’s z-axis to accommodate different lengths of raw material.

10. Tailstock Quill

The tailstock quill, located in the tailstock, has a conical end aligned with the spindle and chuck axis. It provides additional support for long shafts by fitting into a drilled hole in the workpiece, with limited range of motion adjusted by pneumatic or hydraulic pressure.

11. Footswitch or Pedal

Foot pedals are used in CNC lathes to activate and deactivate the chuck and tailstock quill, allowing operators to load and unload parts easily. CNC mills typically do not have foot pedals, as the parts are already supported on the bed.

12. Chuck

The chuck is a lathe-specific component that grips the raw material during machining. It rotates at high speed and typically has three or four pneumatically or hydraulically actuated grips. Three-jaw chucks are self-centering, while four-jaw chucks can be individually adjusted for greater accuracy and eccentric cutting.

13. Control Panel

The control panel includes the input device, display unit, keyboard, and other controls for interacting with the CNC machine. It is often attached to the machine with an extendable arm, allowing operators to position it conveniently.

This comprehensive look at CNC machine components highlights the complexity and precision involved in modern manufacturing processes, ensuring high-quality, accurate production across various industries.

What is Field Programmable Gate Arrays?

Field Programmable Gate Arrays (FPGAs) are semiconductor devices. The lookup table (LUT) is the basic block in every FPGA. Different FPGAs use variable sized LUTs. A lookup table is logically equivalent to a RAM with the inputs being the address select lines and can have multiple outputs in order to get two Boolean functions of the same inputs thus doubling the number of configuration bits. FPGAs can be reprogrammed to desired application or functionality requirements after manufacturing. This differentiates FPGAs from Application Specific Integrated Circuits (ASICs) although they help in ASIC designing itself, which are custom manufactured for specific design tasks. 

In a single integrated circuit (IC) chip of FPGA, millions of logic gates can be incorporated. Hence, a single FPGA can replace thousands of discrete components. FPGAs are an ideal fit for many different markets due to their programmability. Ever-changing technology combined with introduction of new product portfolio is the major drivers for this industry.
